2.3.3. Alarm signals

A. EXCESS BOILER WATER FILLING TIME
The control unit has a waiting time for when the boiler is fi lling with water.
If the level sensor is not covered with water within one minute (two minutes Expression Pro), the control unit safety
control will stop the water fi lling process and the motor.
The signal for the control unit alarm is the fi ve LEDs fl ashing simultaneously. (In all groups).
This alarm signal could be caused by a lack of mains water supply to the machine, an obstruction of the water inlet or a
problem with the control unit that is preventing the signal for automatic water fi lling from being sent.
Warning
This alarm signal is always activated during the fi lling process when this immediately follows
machine installation. This is due to the fact that it takes more than 1 minute to fi ll the boiler. When
this happens, set the switch to zero and return it to the fi lling position in order to continue fi lling
the boiler.

B. NO IMPULSES FROM THE FLOW METER (5 seconds)
If during feed there are no impulses from the fl ow meter, the control unit will detect it and the LED for the selection being
dispensed at that moment will light up and fl ash, but dispensing will not stop.
This alarm signal is produced due to a bypass of the signal from the fl ow meter cover, or due to a poor connection, or
lastly due to some internal problem in the control unit. If this occurs contact the after-sales service.
C. EXCESS FEED FROM THE FLOW METER
If the coffee feed time is over 2 minutes (3 minutes Expression Pro), the control unit detects an excess in the normal coffee
feed time.
Coffee feed will be stopped automatically and the LED for the chosen selection will remain fl ashing.
This alarm signal is either due to an obstruction to the fl ow of water, and the control unit receives slower and more drawn
out impulses than during the normal feed time, or because the coffee is ground very fi nely or packed in the fi lter too
tightly, causing excess weight, thus preventing the water from fl owing with suitable fl uidity.
D. DEPOSIT LEVEL INDICATORS (only portables machines)
This machine has a system for indicating both minimum and maximum levels, which works as follows:
Minimum Level – When the water tank reaches its minimum level, the control unit cuts the current to the
button pad and the heating element, in order to prevent damage to both the element and the pump due
to a lack of water. At that moment the LEDs on the button pad will begin to fl ash, advising the user that
the deposit must be fi lled.
